Study-Unit Description


TITLE Microelectronic Devices

LEVEL 01 - Year 1 in Modular Undergraduate Course


DEPARTMENT Microelectronics and Nanoelectronics

DESCRIPTION The study-unit covers semiconductor materials and technologies; MOS technology; regions of operation of MOS transistors. This study-unit then moves to analysis of d.c. operation, channel length modulation effect, body effect and d.c. biasing in MOS IC design.

The study-unit also covers a.c., small-signal, operation of the MOS transistor, transconductance, , output resistance; capacitances in nanometer-scale transistors; first-order small-signal models.

Bipolar technology is next considered: bipolar transistor structure, vertical npn transistor, lateral pnp transistor, d.c. operation, d.c. biasing, a.c., small-signal operation; junction and diffusion capacitances; first-order small-signal models.

Study-unit Aims:

This study-unit aims at imparting to students knowledge about semiconductor materials and their application in two fundamental microelectronics technologies: MOS and Bipolar.

The unit further aims to familiarise students with properties of the basic active devices used in integrated circuits: the MOS transistor and Bipolar transistor, considered with respect to structure, d.c. operation and a.c. small-signal operation, in the IC design environment.

Learning Outcomes:

1. Knowledge & Understanding:
By the end of the study-unit the student will be able to:

- comprehend physics principles involved that give rise to semiconductor material properties;
- comprehend and analyse the operation and properties of the MOS transistor and the bipolar transistor in the IC design environment.

2. Skills:
By the end of the study-unit the student will be able to:

- carry out d.c. biasing analysis and a.c., small-signal analysis of the MOS transistor and the bipolar transistor in the IC design environment;
- use CADENCE framework software in connection with simulation of d.c. and a.c. reponse of MOS and bipolar transistors.
